The simplest explanation is often the one
[QUOTE=FigLeaf;3321534]She may not be the brightest fish in the pond, but she was bright enough to figure out who I was.
I just wish I knew how she did it because there was NOTHING in the room with my name on it and my wallet was never out of my sight. I am wondering if she pretended like she was my wife or something to the front desk. It's all I can think of.[/QUOTE]Fig, do you have any pics on your profile or that you sent her that you have posted anywhere else, at any time, for any reason? Or that could have been posted by someone else? That would be my first guess. Impersonating your wife at the front desk requires a bit of calculated sange-froide that I doubt many babies have.
Image-googling a picture, however, is the work of a few clicks, and I'm pretty sure I could teach my cat how to do it in an hour or so. Did you call or text her from a phone number that could be googled? Did you leave her alone in your car long enough for her to look at the service receipts in your glove box? There has to be a simpler explanation that you have overlooked.
I'd be astonished if she went from asking for help to actually threatening you with blackmail, but keep the FBI in your back pocket, so to speak, just in case. If she's as UTR as the local brethren seem to indicate, she has left a far wider trail than you have, and it shouldn't be hard to find out who SHE is.
Remember. Cheating on your SO is not a crime. Blackmail is.
Stay strong,
Scott.
